The original version of this article unfortunately contained a mistake.

On page 4, the equation used to calculate model probabilities as a strength of evidence is incorrect.

The corrected equation is given below.

$$ {w_i} = {\hbox{Prob}}\left\{ {{\hbox{model}}\,{g_i}|{\hbox{data}}} \right\} = {\ell_i}/\sum\limits_{{j = 1}}^R {{\ell_j}.} $$

On page 6, the presentation of table 3 was incorrect. The corrected table is given below.
